I tested 2 competitors prior to Cyclone and workout with athletes that have burned through numerous others. This has been the most durable and reliable product on the market. It is the rope of choice in my gym. After months of stuck on no more that 5 reps with other ropes often finding one handle providing different spin rates than the other. I am now regularly hitting 30-40+ with the limiting factor being my own stamina.
